Reverend Clifton Phillips Mandrane, 79, born in Harlem, led a group of African-American passengers in prayer before the start of a bus trip from Brooklyn, N.Y., to Barack Obama's Inauguration in Washington, D.C. He was jailed in 1962 in Albany, Ga., for protesting without a permit. He was jailed with Dr. Martin Luther King for six days with no food. “This trip is a fulfillment of time," he said. "I believe that Americans have achieved the goal of liberty and freedom for all. I couldn’t attend Dr. King's speech and the Million Man March. This is a great opportunity because I am aging. I used to have to ride the back of the bus - but we fought it through protest and the courts. This is about change. Today the battlefield of the civil-rights movement is in the public schools. If we don’t help young people, we won’t have future leaders. Justice for all - that is what democracy is!" Jan. 18, 2009.
